Headless Shopify Replatforming: Delivering a 300% Speed Boost & 42% Conversion Lift

A premium lifestyle brand with over 80,000 monthly shoppers was limited by an antiquated monolithic Shopify theme that took 5.2 seconds to load on mobile devices.

Architectural Modernization

We completely decoupled the frontend using Next.js on Vercel, integrating Sanity for rich storytelling and Shopify GraphQL Storefront API for inventory and secure checkout.

• Average page load time decreased from 5.2s down to 1.1s on 4G connections
• Mobile conversion rate climbed by 42% in the first 60 days following launch
• Editorial team gained real-time visual landing page construction via Sanity Studio
• Organic search rankings rose across 120+ targeted apparel keywords
